Color Sensor
Programming Blocks
| Block | Function |
|---|---|
 |
It will return the color sensor value, the number is lower on white surfaces and increases as the surface gets darker. |
 |
It will compare the sensor value with the set value and return a logic (true/false) result. |

Sample Code
Result: The returning value of the sensor will be shown on the display.
P Controller Line Follower
Hardware Connection: connect the motors and sensors as the sample robot instructions which can
be found at:

Result: The robot can follow a line smoothly.
Note: The factor of the P controller is 0.2 in this code, which can be adjusted based on robot
performance. Also, the speed of the line following is 400.
